Abstract
Objective: To evaluate the short-term and long-term efficacy of endoscopic submucosal dissection (ESD) in the treatment of early low rectal cancer and precancerous lesions. Methods: Inclusion criteria: (1) Distance from the lower margin of tumor to the anal was ≤ 5 cm. (2) Early low rectal cancers were any size rectal epithelial tumors with infiltration depth limited to the mucosa and submucosa, which were diagnosed by postoperative pathology as high-grade intraepithelial neoplasia or adenocarcinoma of the rectum with infiltration depth of intramucosal or submucosal cancer (M or SM stage). (3) Precancerous lesions included adenoma and low-grade intraepithelial neoplasia of the rectum. (4) Patients received ESD treatment. Patients with tumor invasion depth over submucosa by pathology were excluded. From January 2008 to January 2018, 63 patients meeting the above criteria in Peking University First Hospital were enrolled in this descriptive cohort study. The disease characteristics, clinical manifestations, pathological types, treatment time, hospitalization time, en bloc resection rate (resection of the whole lesion), complete resection rate (both the horizontal and vertical incision margins were negative), postoperative complications and follow-up results were analyzed. Cummulative survival rate was calculated by Kaplan-Meier. Results: The diameter of the lesion was (29.0±23.4) mm and the distance from the lesion to the anus was (2.7±1.8) cm. The median operation time was 45.0 (range, 10.0 to 360.0) minutes, the median hospitalization time was 3.0 (range, 2.0 to 12.0) days, en bloc resection rate was 100%, complete resection rate was 96.8% (61/63), and 1 case (1.6%) had postoperative bleeding. The follow-up rate was 87.3% (55/63) and the median follow-up time was 57.9 (range, 15.6 to 121.1) months. No local recurrence was found during the follow-up period and the 5-year survival rate was 100%. Conclusion: Short- and long-term efficacy of ESD are quite good in the treatment of patients with early low rectal cancer and precancerous lesions.

Abstract
Objective: To analyze the concordance of KRAS, NRAS, BRAF and PIK3CA gene mutations detected in plasma and matched tumor tissues in colorectal cancer patients, in order to provide good evidences to support plasma could be a potential surrogate of tumor tissue for gene mutation test. Methods: One hundred and seventy-five cases of colorectal cancer were collected at the First Hospital of Jilin University, from October 2016 to October 2017.There were 101 males and 74 females, their ages ranged from 28 to 85 years,with median age of 59 years. The KRAS, NRAS, BRAF and PIK3CA gene mutations in the plasma and paired tumor specimens of all patients were detected by next generation sequencing. Results: The results of tissue samples test were gold standard. Comparison of the four genes showed that concordance rates between plasma and tissue samples were 81.1%(Kappa=0.543), 99.4%(Kappa=0.886), 99.4% (Kappa=0.886) and 97.7%(Kappa=0.714) respectively for KRAS, NRAS, BRAF and PIK3CA. The plasma detection rates of these genes were related to tumor stage(P=0.001), but not to gender(P=0.468) and age(P=1.000) of patients. Conclusions: The study shows a high concordance of KRAS, NRAS, BRAF and PIK3CA gene mutations in plasma against mutation status in tumor tissue. In colorectal cancer, tumor tissue remains the best specimen for gene detection. However, patients from tumor tissue specimens cannot be obtained, especially those with advanced metastases, plasma can be used instead of tissue to detect the mutation status of KRAS, NRAS, BRAF and PIK3CA to guide targeted therapy.

Abstract
Objective: To investigate the correlation between serum interleukin-38 (IL-38) and acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with pulmonary embolism (PE). Methods: The 94 patients with AECOPD admitted to Tianjin Chest Hospital from August 2015 to April 2018 were suspected of PE. They were divided into two groups based on CT pulmonary angiography (CTPA) and color Doppler ultrasound of lower extremity veins: 39 cases in PE group and 55 cases in Non-PE group. The general data and laboratory examination results of these subjects were recorded. Serum IL-38 was measured by double antibody enzyme-linked immunosorbent assays (ELISA). The between-group differences of above parameters were analyzed. Pearson correlation or Spearman rank correlation was used to analyze the association of IL-38 with each variable in AECOPD patients. Binary Logistic regressions were conducted to determine the risk factors of AECOPD with PE. ROC curve was used to assess the value of serum IL-38 in predicting AECOPD with PE. Results: The serum level of IL-38 was lower in PE group than in Non-PE group [46.3 (33.1, 58.1) vs 61.5 (46.6, 72.5) ng/L, P<0.05]. Correlation analysis showed that serum IL-38 levels were negatively correlated with C reactive protein and fibrinogen in patients with AECOPD (r=-0.38,-0.29, all P<0.05). Binary Logistic regressions showed that lower serum IL-38 level was a risk factor of AECOPD with PE (OR=0.78, 95%CI: 0.61-0.94, P<0.05). The area under the ROC curve was 0.74 (95% CI: 0.63-0.84, P<0.05). When cutoff value of serum IL-38 was 52.1ng/L, the sensitivity was 70.9% and the specificity was 69.2% respectively. Conclusion: IL-38 could relieve the hypercoagulability by inhibiting inflammation in patients with AECOPD and could act as a predictor of AECOPD with PE.

Abstract
Objective: To investigate the epidemiologic and behavioral characteristics of HIV among community population in Liangshan prefecture. Methods: We collected social demographic, behavioral and serological information by means of the monitoring questionnaire and serological tests. Data was analyzed by using the chi-square test and logistic regression. Results: From April to June of 2010 to 2015, 14 092 cases of community population were selected as the study objects, with 267 cases diagnosed as HIV positive patients. The HIV positive rates were 3.24%, 3.07%, 1.17%, 1.38%,1.42% and 1.25%, respectively. We observed that when community population having the following characteristics as: living in Butuo country (OR=3.83), being males (OR=1.77), being Yi nationality (OR=4.40) being widowed (OR=28.57), with history of drug abuse (OR=3.71) or injecting drug use (PWID) (OR=4.92), or history of needle sharing among PWID (OR=8.53), were under higher risks for HIV infection. With histories as: having had secondary or above levels of schooling (OR=0.59), having protected sex with regular partners (OR=0.21) and with non-regular partners (OR=0.46), they seemed to be somehow protected for getting HIV infection. Conclusion: The positive HIV rates of HIV among community population in Dechang, Ningnan and Butuo varied from 0.10% to 8.77% while the HIV transmission among general population remained challenging.

Abstract
Objective: To investigate the clinical pathologic characteristics of extranodal follicular dendritic cell sarcoma (FDCS). Methods: We collected 7 cases of extranodal FDCS, HE staining, immunohistochemical study were performed. The V600E mutation of BRAF in 7 cases were detected by real-time PCR and EBER in situ hybridization was performed on 4 cases. Results: Among the 7 cases of FDCS, 5 cases were male and 2 cases were female, the median age was 55 years old, including 4 cases of low-grade FDCS and 3 cases of high-grade FDCS. The tumor location of 2 cases was in mediastinum, the tumor locations of others were in nasopharynx, kidney, lung, rectum and liver, respectively. The results of immunohistochemistry showed that, the tumor cells were diffusely or focally positive for CD21, CD23, CD35, D2-40, EGFR and CXCL13, but negative for S-100, CD68, HMB45, SMA, Desmin, CD117, Dog-1, CD34, CD30, EMA and CK.Five cases were positive for PD-L1 and the its expression in high-grade FDCS were higher than that in low-grade FDCS.Two cases of low-grade FDCS were positive for BRAF V600E, but the BRAF V600E mutation weren't detected in all of 7 cases. The result of EBER in-situ hybridization showed that only the nasopharynx FDCS was positive.The follow-up information of 5 patients were available (7~43 months), 4 patients died and 1 still alive with rectum metastasis. Conclusions: FDCS is a rare malignant disease with relapse and metastatic tendency. The combined applications of the first-line antibodies including CD21, CD23, CD35 and second-line antibodies including D2-40, CXCL13, EGFR are helpful for its diagnosis and differential diagnosis. The high expression of PD-L1 implicates the potential benefit of FDCS patients acquired from immunotherapy.

Abstract
OBJECTIVE To discuss the clinical characteristics and diagnostic and therapeutic considerations of primary thyroid lymphoma (PTL) by reviewing PTL cases. METHODS In the study, 12 cases of PTL diagnosed and treated in Peking University First Hospital between January 1995 and September 2015 were identified. The clinical characteristics, management experiences and prognosis of these cases were reviewed retrospectively. RESULTS A total of 12 PTL patients (four males and eight females) were collected, with an average age of 63 years (42 to 81 years) at the time of diagnosis. The average time to clarify diagnosis was 5 months (0.5 to 24 months). Eleven patients presented with a rapidly growing neck mass and visited surgical department, except one complained of coughing and suffocated. Seven patients were hypothyroid, and four were euthyroid at the time of diagnosis. In sonography of 11 cases, nine showed bilateral nodules, with an average diameter of 3.87 cm. Pathologic diagnosis of non-Hodgkin's lymphoma was confirmed in all the 12 cases by means of partial thyroidectomy (four) or core needle biopsy (eight). The pathological subtypes were diffuse large B cell lymphoma in nine patients, mucosa-associated lymphoid tissue lymphoma (MALToma) in two, and small B cell lymphoma in the other one patient. Five patients were concomitant with Hashimoto's thyroiditis. Eleven patients received chemotherapy. Only one patient did not have any further treatment after operation due to an inertia type of tumor. The median overall survival time was 24 months (1-117 months), three patients died. Among the patients who survived, seven completed chemotherapy without disease progression, one MALToma case did not receive chemotherapy after thyroidectomy but was still alive with PTL, and one patient just finished his second course of chemotherapy. CONCLUSION The diagnosis of PTL should be considered when dealing with rapidly growing goiters in elder female Hashimoto's thyroiditis patients whose B ultrasound indicates hypoechogenicity in thyroid nodules or parenchyma, especially with lymphadenopathy and tracheal compressions. Timely use of coreneedle biopsy on suspicious cases can avoid unnecessary surgical trauma, and chemotherapy is the main treatment.

Abstract
Hypertension results from the interaction of genetic and acquired factors. IgG occurs in the form of different subclasses, of which the effector functions show significant variation. The detailed differences between the glycosylation profiles of the individual IgG subclasses may be lost in a profiling method for total IgG N-glycosylation. In this study, subclass-specific IgG Fc glycosylation profile was investigated in the four northwestern Chinese minority populations, namely, Uygur (UIG), Kazak (KZK), Kirgiz (KGZ), and Tajik (TJK), composed of 274 hypertensive patients and 356 healthy controls. The results showed that ten directly measured IgG N-glycan traits (i.e., IgG1G0F, IgG2G0F, IgG2G1FN, IgG2G1FS, IgG2G2S, IgG4G0F, IgG4G1FS, IgG4G1S, IgG4G2FS, and IgG4G2N) representing galactosylation and sialylation are significantly associated with hypertension, with IgG4 consistently showing weaker associations of its sialylation, across the four ethnic groups. We observed a modest improvement on the AUC of ROC curve when the IgG Fc N-glycan traits are added into the glycan-based model (difference between AUCs, 0.044, 95% CI: 0.016-0.072, P = 0.002). The AUC of the diagnostic model indicated that the subclass-specific IgG Fc N-glycan profiles provide more information reinforcing current models utilizing age, gender, BMI, and ethnicity, and demonstrate the potential of subclass-specific IgG Fc N-glycosylation profiles to serve as a biomarker for hypertension. Further research is however required to determine the additive value of subclass-specific IgG Fc N-glycosylation on top of biomarkers, which are currently used.

Abstract
Objective: To explore whether Integrated Early Childhood Development (IECD) program has effectively improved the nurturing care for children aged 0-35 months in rural China. Methods: IECD has been implemented by the government of China with support from the United Nations Children's Fund (UNICEF) in four poverty-stricken rural counties since 2014. The interventions targeting the five key components of nurturing care (i.e. child and caregiver health, child nutrition, early learning support, child protection and social security) were delivered through the IECD program to children aged 0 to 35 months and their caregivers. A population-based intervention trial was designed to evaluate intervention effectiveness with data collected in 2013 (baseline) and 2016 (mid-term). The changes of nurturing care in the intervention and control group were analyzed by using a difference-in-differences (DID) model. This approach provided adjustment for sociodemographic and other confounding factors. Results: The baseline and mid-term survey enrolled 1 468 and 1 384 children in the intervention group, and 1 485 and 1 361 in the control group. After two years of implementation, the prevalence of caregiver's depression in the intervention group showed a decrease of 9.1% (mid-term 34.8% (479/1 377) vs. baseline 43.9% (621/1 414)), whereas that in control group showed a decrease of 1.6% (mid-term 34.3% (464/1 353) vs. baseline 35.9% (509/1 419)). With the confounding adjusted in the difference-in-differences model, the decrease of the caregiver's depression prevalence in the intervention group was 7.0% greater than that in the control group (P=0.008). The qualified rate of minimum meal frequency in the intervention group showed an increase of 10.4% (mid-term 69.0% (532/771) vs. baseline 58.6% (481/821)), whereas the qualified rate in the intervention group showed an increase of 2.9% (mid-term 66.4% (469/706) vs. baseline 63.5% (508/800)). With the confounding adjusted in the difference-in-differences model, the increase of the qualified rate in the intervention group was 8.2% greater than that in the control group (P=0.021). The proportion of violent discipline by caregivers in the intervention group showed a decrease of 6.2% (mid-term 49.1% (478/973) vs. baseline 55.3% (554/1 001)), whereas the proportion in control group showed an increase of 4.5% (mid-term 58.4% (560/959) vs. baseline 53.9% (558/1 036)), and with the confounding adjusted in the difference-in-differences model, the difference in increase rate between two groups was 11.0% (P=0.001). The proportion of families with three or more children's books in the intervention group showed an increase of 12.7% (mid-term 42.7% (588/1 378) vs. baseline 30.0% (432/1 440)), whereas the proportion of the control group showed an increase of 4.2% (mid-term 25.7% (349/1 357) vs. baseline 21.5% (298/1 388)), and with the confounding adjusted in the difference-in-differences model, the difference in increase rate between two groups was 6.1% (P=0.007). Conclusions: The IECD intervention strategy implemented in rural China effectively improved the mental health of caregivers, optimizes families' child feeding and early stimulation behaviors, while reducing violent discipline and other risk factors. IECD provides better nurturing care for the early development of children aged 0-35 months in rural China.

Abstract
Objective: To investigate the predictive value of early lactate area for mortality in elderly patients with septic shock. Methods: From January 2012 to December 2013, a prospective study was conducted in the Department of Critical Care Medicine, Qilu Hospital of Shandong University. A total of 115 septic shock patients with age ≥65 years were included in the study. Serum lactate was measured every 6 hours, the lactate indicators, including early lactate area, APACHE Ⅱ score etc were recorded. Results: The overall 28-day mortality rate was 67.0%. The top three primary infection sources were lung, abdominal cavity and bloodstream. When compared to survivors, non-survivors had significantly elevated early lactate area and APACHE Ⅱ score and lowered lactate clearance[(27.4±7.6) vs ( 20.3±6.5)], they were significantly more likely to have undergone mechanical ventilation, renal replacement therapy and inotropic or vasopressor support for ≥3 d, and more frequently displayed signs of cardiovascular, respiratory, and renal and hepatic dysfunction (all P<0.05) .Receiver Operating Characteristic curves indicated the lactate area score displayed a strong predictive power for 28 day mortality as indicated by an AUC of 0.758 (P<0.01) and had significantly greater predictive power when compared to the initial lactate or lactate clearance (all P<0.05). Conclusions: In geriatric patients with septic shock, the early lactate area is a useful predictor for early death and showed better predictive value than other lactate indicators.

Abstract
Objective: To evaluate the predictive value of MRI features and pathological parameters on local recurrence, metastasis and progression free survival (PFS) for locally advanced rectal cancer after neoadjuvant chemoradiotherapy and subsequent total mesorectal excision surgery. Methods: A retrospective analysis of 95 patients with locally advanced rectal adenocarcinoma who underwent total mesorectal excision after neoadjuvant chemoradiotherapy was performed. Univariate and multivariate analyses were performed to evaluate the predictive value of MRI features before chemoradiation and postoperative pathological parameters on progression free survival. Results: Among the 95 cases, 5 cases occured local recurrence, 21 cases developed, 3 cases including both locally recurrence and distant metastasis, 19 died and 47 had no recurrence or metastasis at the last of follow-up. Univariant analysis showed that MRI signs before chemoradiation, namely, mr circumferential resection margin, mr levator ani muscle invasion, mr lymphatic vessel invasion, mr tumor deposition and postoperative pathological parameters, yp circumferential resection margin, yp lymphatic vessel invasion were related to PFS (P<0.05). Multivariate analysis of Cox proportional hazard model showed that mr lymphatic vessel invasion and mr tumor deposition were independent factors for PFS (OR=2.774 and 3.029, P<0.05). Conclusions: Lymphatic vessel invasion and tumor deposition on MRI are independent prognostic factors for progression free survival of locally advanced rectal cancer after neoadjuvant chemoradiotherapy and TME surgery. To some extent, MRI signs can assess local recurrence and distant metastasis in locally advanced rectal cancer patients after neoadjuvant chemoradiotherapy and mesorectal excision.

Abstract
Objective: To investigate the magnetic resonance imaging (MRI) findings and clinicopathological features of primary lesions in patients with occult breast cancer (OBC). Methods: The imaging reports from the Breast Imaging Reporting and Data System in 2013 were retrospectively analyzed to investigate the morphology and the time signal intensity curve (TIC) of breast lesions in patients with OBC. The clinical and pathological characteristics of these patients were also included. Results: A total of 34 patients were enrolled. Among these patients, 24 patients underwent modified radical mastectomy and 18 of them had primary breast carcinoma in pathological sections. MRI detected 17 cases of primary lesions, including six masse lesions with a diameter of 0.6-1.2 cm (average 0.9 cm), and 11 non-mass lesions with four linear distributions, three segmental distributions, three focal distributions, and one regions distribution. Five patients had TIC typeⅠprimary lesions, ten had TIC type Ⅱ primary lesions, and two had TIC type Ⅲ primary lesions. Among all 34 cases, 23 of them had complete results of immunohistochemistry: 11 estrogen receptor (ER) positive lesions (47.8%), tenprogesterone receptor (PR) positive lesions (43.5%), seven human epidermal growth factor receptor 2 (HER-2) positive lesions (30.4%), and 20high expression(>14%) of Ki-67 (87.0%). The proportion of type luminal A was 4.3%, type luminal B was 43.5%, triple negative breast cancer (TNBC) was 30.4%, and HER-2 over expression accounted for 21.7%. Conclusions: The primary lesions of OBC usually manifested as small mass lesions, or focal, linear or segmental distribution of non-mass lesions. The positive rate of ER and PR was low, but the positive rate of HER-2 and the proliferation index of Ki-67 was high. Type luminal B is the most common molecular subtype.

Abstract
Objective: To analyze the treatment of advanced non-small cell lung cancer (NSCLC) with performance status (PS) scores between 2 and 4, in order to improve the diagnosis and treatment of these patients. Methods: A total of 36 patients with advanced NSCLC with hypoxemia were reviewed. The clinical data of disease characteristics, etiology, complications, manifestation, therapy, progression, and secondary biopsy were collected. The clinical efficacy was graded according to the Response Evaluation Criteria In Solid Tumors (RECIST): complete response (CR), partial response (PR), stable disease (SD) and disease progression (PD). Results: All patients had hypoxemia, of whom 86.1% (31 patients) had complications and 55.6% (20 patients) had noninvasive ventilator for respiratory support. 77.8% (28 cases) received broad-spectrum antibiotic treatment, and 78.6% of them got lung osmotic relief after the anti-infection treatment. 15 cases received bedside fiberoptic bronchoscopy suction, of whom two cases were treated with airway stent deposition due to airway obstruction, four cases with thoracic drainage, four cases with anticoagulation, and one with thrombolytic therapy. After these supportive treatment, the PS score of these patients decreased from 3.4±0.5 to 2.5±0.7, while SPO(2) improved from (89.0±5.2)% to (95.0±3.5)%. As first-ling anti-cancer treatment, nine patients were administrated with targeted medicine orally, 13 patients with a combined chemotherapy of pemetrexed plus bevacizumab or carboplatin, eight patients with paclitaxel plus carboplatin, four patients with gemcitabine plus carboplatin, and two patients with docetaxel plus gemcitabine. In the first response evaluation, there were one case of CR, 23 cases of PR, four cases of SD, and eight cases of PD, with a clinical benefit rate of 66.7% and a disease control rate of 77.8%. A total of 22 patients experienced disease progression, of whom eight cases had a secondary biopsy and six cases had gene sequencing. Of these 36 patients, 10 (27.8%) patients survived at the last follow-up, with a progression-free survival of (10.0±6.5) months. Conclusion: Besides prompt anti-cancer treatment and best supportive treatment should be incorporated to improve PS and improve outcome.

Abstract
OBJECTIVE To estimate the prevalence and trend of autism spectrum disorders (ASD) in children aged 0-6 years in China. METHODS Systematic literature searches were conducted in PubMed, Web of Science, Scopus, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Wanfang and Weipu Database (VIP ), and the literatures published before February 25, 2017 were selected according to the same criteria. Prevalence Data of three periods were abstracted, then pooled using random effect model. Subgroup analysis was done across data resource, age group, screening criteria, diagnostic criteria, and literature quality. RESULTS In the study, 9 ASD studies and 20 autism (also known as autistic disorder, AD) studies were eligible for review. The pooled prevalence of AD in children aged 0-6 years in 2006-2010 and 2011-2015 was 1.74 ‰ (95%CI: 1.12‰-2.69‰) and 1.80‰ (95%CI: 1.33‰-2.43‰), and there was no significant difference between the two groups (P=0.898), but they were higher than 0.94‰ (95%CI: 0.67‰-1.33‰) in 1996-2005 (P=0.031; P=0.005) significantly. The pooled prevalence of ASD in children aged 0-6 years was 3.52 ‰ (95% CI: 1.48‰-8.34‰) and 3.48‰ (95%CI: 1.77‰-6.84‰) in 2006-2010 and 2011-2015, respectively, and the difference between the two periods was not significant (P=0.983). There was no significant difference between the pooled prevalence in the three periods among the boys, and girls' too. The pooled prevalence of ASD in children aged 0-6 years was 3.51‰ (95%CI: 2.15‰-5.74‰) and AD was 1.77‰ (95%CI: 1.40‰-2.24‰) in 2006-2015, with prevalence ratios of boys to girls 2.59:1 and 3.63:1, respectively. The pooled prevalence of AD was lower in 0-6 years children than in other age groups and higher in high-quality studies than in low-quality studies, which was the same as ASD. Data resource, screening and diagnostic criteria were not significantly related with the pooled prevalence of AD and ASD. CONCLUSION The prevalence of ASD and AD in children aged 0-6 years in China from 2006 to 2015 was stable, and there was not enough evidence to prove that it was higher than before 2005. National survey and monitoring of early childhood autism should to be conducted.

Abstract
Many studies have evaluated the correlation between peptidylarginine deiminase 4 (PADI4) -92C/G polymorphism and rheumatoid arthritis (RA), but the results remain inconclusive. Therefore, we performed a meta-analysis in the Chinese population to provide comprehensive data on the association between PADI4 -92C/G polymorphism and RA. Eligible studies published before May 2016 were identified in PubMed and Chinese databases. The strengths of these associations were assessed by pooled odds ratios (OR) and 95% confidence interval (CI). Eight studies documenting a total of 1351 RA cases and 1585 controls were included in this meta-analysis. In the overall analysis, a significant association between the PADI4 -92C/G polymorphism and RA was found in the Chinese population (G vs C: OR=1.32, 95%CI=1.02-1.71; GG+CG vs CC: OR=1.75, 95%CI=1.20-2.53). The subgroup analyses stratified by geographic area(s) and source of controls revealed significant results in South China, in hospital-based studies and population-based studies. In summary, this meta-analysis suggested that PADI4 -92C/G polymorphism may be associated with the RA incidence in the Chinese population, especially for South China. Further studies conducted on other ethnic groups are required for definite conclusions.

Abstract
Objective: To explore the value of histopathologic diagnosis after colposcopy for high-risk HPV16/18 positive patients with negative cytology or atypical squamous cells of undetermined significance (ASCUS) for early screening of cervical lesions. Methods: A retrospective study of cervical histopathologic diagnosis in the HPV16/18 positive patients received colposcopy evaluation before got the histology was carried out between January 2014 and January 2016. The cytology of the patients should be negative or ASCUS. A total of 337 patients with age from 21 to 65 years old were enrolled, including 214 patients with negative cytology, and 123 patients with ASCUS. Results: (1) The results of pathology were as follows: 63 (18.7%) cases inflammation, 89 (26.4%) cases cervical intraepithelial neoplasia (CIN)Ⅰ, 182 (54.0%) cases CINⅡ-Ⅲ and adenocarcinoma in situ (AIS), and 3 (0.9%) cases minimal invasive cancer (stageⅠa1). The incidence of CINⅡ and above cervical lesions was higher in the patients with ASCUS (71.5%, 88/123) than that in the patients with negative cytology (45.3%, 97/214; χ(2)=24.876, P<0.01), and it was higher in the patients with HPV16 positive (64.4%, 150/233) than that in the patients with HPV18 positive (30.3%, 27/89; χ(2)=31.388, P<0.01). There was statistically significant difference among the different age group in which the patients of 20-29 years old was 69.3% (52/75), 30-39 years old was 55.1% (75/136), 40-49 years old was 44.8% (30/67) and 50 years old and above was 47.5% (28/59; χ(2)=16.512, P=0.032). (2) Among the patients with negative cytology, the incidence of CINⅡ and above cervical lesions in the patients with HPV16 positive was higher than that in the patients with HPV18 positive [54.8% (80/146) vs 26.0% (20/77) ; χ(2)=16.930, P<0.01]. The incidence was also higher in the patients with HPV16 positive than that in the patients with HPV18 positive [76.5% (78/102) vs 55.6% (15/27) ; χ(2)=4.642, P=0.031] among the patients with ASCUS. (3) Compared to the patients diagnosed inflammation or CINⅠ, the patients diagnosed CINⅡ and above cervical lesions had higher infection rate of HPV16, lower infection rate of HPV18, higher incidence of ASCUS, and smaller parities (all P<0.05). A multifactor analysis was carried out, the results showed that HPV16 positive and ASCUS might be independent risk factors to predict the incidence of CINⅡ and above cervical lesions (P<0.01) . Conclusions: The incidence of cervical precancerous lesions is high in the women with HPV16/18 infection. Patients with HPV16 infection are more likely to have the CINⅡ and above cervical lesions than patients with HPV18 infection. Patients with HPV16/18 infection are suggested to be directly transferred to clinic of colposcopy, and then getting the histology selectively, which would be help to early detection of the cervical precancerous lesions.

Abstract
This study was conducted to evaluate the effects of supplemental rumen-protected capsule (RPC) on animal performance, serological indicators, and serum heat shock protein 70 (HSP70) of lactating Holstein cows under heat stress (HS). During summer months, 30 healthy multiparous lactating Holstein cows with a parity number of 3.1 ± 0.44, 70 ± 15 d in milk, an average body weight of 622 ± 62kg, and an average milk yield of 32.28 ± 0.96kg/d, were used. The cows were randomly allocated to two groups: a control group and an RPC-supplemented group (0.13373kg K2SO4, 0.02488kg vitamin C, 0.021148kg niacin, and 0.044784kggamma-aminobutyric acid per cow). During the 42-d experiment, ambient air temperature and relative humidity inside and outside the barn were recorded hourly every day for the determination of temperature-humidity index (THI). Milk and blood samples were collected every week, and body weight and body condition scoring were measured on day 0. Based on the THI values, the animals had moderate HS. On day 42, the RPC group had lower HSP70, adrenocorticotropic hormone (P = 0.0001), lactate dehydrogenase (P = 0.0338), and IL-6 (P = 0.0724) levels than the control group, with no significant differences in creatine kinase, glucocorticoid, or IL-2 levels. Milk yield, energy-corrected milk, and dry matter intake were higher in RPC than in the control group (P = 0.0196). There were no significant differences in milk fat or daily protein levels between the two groups; however, daily protein and milk fat levels were higher in the RPC group than in the control group (P = 0.0114 and P = 0.0665, respectively). Somatic cell counts were no different between the two groups. In conclusion, RPC may alleviate HS and improve dairy cow performance.

Abstract
Objective: To explore the effect and possible mechanisms of intermittent alkaline on rat vascular smooth muscle cells (VSMCs) calcification induced by high phosphorus. Methods: VSMCs were isolated from rat thoracic aorta and cultured in vitro. The fourth generation VSMCs were randomly divided into control group, high phosphorus+ pH7.4, high phosphorus+ pH7.5, high phosphorus+ pH7.6 and high phosphorus+ pH7.7 group with random number table. The control group was cultured in DMEM with 10% fetal bovine serum. Other groups were cultured in DMEM with 10 mmol/L β-glycerophosphate and alkalized by 7.4% NaHCO(3) to adjust the pH respectively. After the intervention of 4 hours, the control group was replaced with the normal medium containing 10% fetal bovine serum, the other 4 groups were replaced with high phosphorus based on the pH value of the culture medium, and then replaced the culture medium every other day. After 4 days intervention, the mRNA and protein expression of L type calcium channel β(3) subunit(LTCC β(3)) and Runt related transcription factor 2 (Runx2) were detected by RT-PCR and Western blot. After 4 days intervention, the level of VSMC calcium ion was detected by Fluo-3/AM. After 14 days intervention, alkaline phosphatase (ALP) activity was measured by enzyme linked immunosorbent assay (ELISA) and the calcification was observed by measuring calcium content. Results: (1) Compared with control group, the gene and protein expressions of LTCC β(3) were higher in high phosphorus+ pH7.4 group (0.49±0.03 vs. 0.23±0.02 and 0.45±0.03 vs. 0.26±0.02 respectively, all P<0.05). Compared with high phosphorus+ pH7.4 group, the mRNA(0.86±0.05) and protein(0.62±0.04) expressions of LTCC β(3) were higher in high phosphorus+ pH7.5 group (P<0.05). Compared with high phosphorus+ pH7.5 group, the mRNA(0.99±0.05) and protein(0.80±0.03) expressions of LTCC β(3) were higher in high phosphorus+ pH7.5 group (all P<0.05). Compared with high phosphorus+ pH7.6 group, the mRNA(1.16±0.05) and protein(0.93±0.03) expressions of LTCC β(3) were higher in high phosphorus+ pH7.7 group (all P<0.05). (2) Compared with control group, calcium ion influx were higher in high phosphorus+ pH7.4 group (124.61±6.06 vs. 75.68±7.82, P<0.05). Compared with high phosphorus+ pH7.4 group, calcium ion influx was higher in high phosphorus+ pH7.5 group(210.85±9.75, P<0.05). Compared with high phosphorus+ pH7.5 group, calcium ion influx was higher in high phosphorus+ pH7.6 group(298.44±11.42, P<0.05). Compared with high phosphorus+ pH7.6 group, calcium ion influx was higher in high phosphorus+ pH7.7 group(401.13±11.41, P<0.05). (3) Compared with control group, the mRNA and protein expressions of Runx2 and ALP were higher in high phosphorus+ pH7.4 group (0.60±0.04 vs. 0.34±0.03, 0.42±0.04 vs. 0.21±0.02, 67.2±4.3 vs. 23.2±2.3 respectively, all P<0.05). Compared with high phosphorus+ pH7.4 group, the mRNA(0.76±0.05) and protein(0.68±0.03) expressions of Runx2 and ALP(102.1±5.4) were higher in high phosphorus+ pH7.5 group (all P<0.05). Compared with high phosphorus+ pH7.5 group, the mRNA(0.90±0.05) and protein(0.90±0.05) expressions of Runx2 and ALP(139.3±4.9) were higher in high phosphorus+ pH7.6 group (all P<0.05). Compared with high phosphorus+ pH7.6 group, the mRNA(1.11±0.05) and protein(1.08±0.06) expressions of Runx2 and ALP(197.0±6.7) were higher in high phosphorus+ pH7.7 group (all P<0.05). (4) Compared with control group, the calcium content were higher in high phosphorus+ pH7.4 group ((75.4±4.3)mg/g pro vs.(25.2±2.1)mg/g pro, P<0.05). Compared with high phosphorus+ pH7.4 group, the calcium content were higher in high phosphorus+ pH7.5 group ((100.8±5.7) mg/g pro, P<0.05). Compared with high phosphorus+ pH7.5 group, the calcium content were higher in high phosphorus+ pH7.6 group ((143.5±6.1) mg/g pro, P<0.05). Compared with high phosphorus+ pH7.6 group, the calcium content were higher in high phosphorus+ pH7.7 group ((205.1±8.2) mg/g pro, P<0.05). Conclusion: Intermittent alkaline stimulation can promote high phosphorus induced rat VSMCs calcification possibly through upregulating LTCC β(3) subunit gene and protein expression, increasing calcium ion influx and enhancing VSMCs phenotypic transformation.

Abstract
Objective: To observe the clinicopathologic features and prognosis of prostate cancer (PCa) in young men. Methods: Twenty-eight early onset (≤55 years) patients with PCa pathologically confirmed in the Peking University Third Hospital and Peking University Shougang Hospital from January 1st 2000 to August 31st 2016 were collected. There were 18 radical prostatectomy (RP) cases and 10 transrectal prostatic biopsy cases. Contemporaneously, 445 elderly (>55 years) patients were collected, of which 385 had detailed pathological information, were chosen as control group. The mean age of young group was 51 years (29-55 years). Follow-up data for 22 cases were available (1-110 months). The correlation of the clinicopathological features and prognosis were analyzed retrospectively. Results: Presurgical prostatic specific antigen (PSA) level was abnormal in young patients, with 18 cases (64.3%) had elevated fPSA level, 26 (92.9%) had increased tPSA level, and 26 (92.9%) had decreased fPSA/tPSA ratio. Gleason score (GS) was 8 in 10.7% (3/28) of cases, and 9 in 42.9% (12/28) of cases. Of the 18 patients with RP, 17 (94.4%) had pT stage ≥pT2c. PSA level (P=0.006) and GS (P=0.001) were positively correlated with pT stage. Family history of PCa in 1st degree relatives was found in 9.1% of the cases. During follow-up, 2 patients died of PCa, 7 patients showed progression within 24 months. There were no significant differences in PSA level and GS between young patients and elderly patients, while the former group was more likely to have incontinence (P=0.023), higher PSA levels (P=0.001), and lower overall survival (P=0.049). Only postsurgical PSA level was found to be negatively associated with overall survival (P=0.030) and cancer specific survival (P=0.021) in young patients. Conclusions: Presurgical PSA level and GS are positively correlated with pT stage of early onset PCa. Compared with elderly patients, young patients are more likely to have incontinence, higher postsurgical PSA level, and lower overall survival. Among all the parameters, only postsurgical PSA level shows an adverse impact on prognosis of early onset PCa. Young patients, especially those with family history, may benefit from studies on the susceptibility loci and phenotype of PCa.

Abstract
Objective: To explore the expression of CD55 in liver tissue of trichloroethylene-sensitized mice and discuss the role of CD55 in the liver immune injury of trichloroethylene-sensitized mice. Methods: 6-8 weeks specific pathogen free female BALB/c were randomly divided into blank control group, solvent control group and TCE treatment group to establish BALB/c mice sensitized model. According to mouse skin sensitization reaction score, TCE treatment mice were divided into sensitized and non-sensitized group at 24 h after the last challenge. At 48 h after the last challenge, the blood and aseptic livers were collected. The level of serum ALT was tested by automatic biochemical analyzer and pathology of the liver was observed. C5b-9 deposition was studied by immunohistochemistry (IHC) . CD55 protein expression level in liver tissue was studied by immunohistochemistry and Western blotting. The expression of CD55 mRNA in liver tissue was detected by qRT-PCR. Results: Liver function test result showed level of serum ALT in TCE sensitized group was significantly higher than solvent control group and TCE non-sensitized group (P<0.05) . There was ballooning degeneration and necrosis of liver cells in TCE sensitized group. IHC demonstrated that TCE sensitized group had obviously increased content of C5b-9 but had reduced content of CD55 compared with solvent control group and TCE non-sensitized group (P<0.05) . Western blotting also showed that TCE sensitized group had lower expression of CD55 than solvent control group and TCE non-sensitized group (P<0.05) . qRT-PCR showed that CD55 mRNA expression level in liver tissue of TCE sensitized group was apparently lower than solvent control group and TCE non-sensitized group (P<0.05) . Conclusion: Complement activation may be involved in TCE-induced liver injury, and the expression change of complement regulatory protein CD55 may play essential role in the process.

Abstract
Objective:To compare larynx preservation rate, local control rate, overall survival rate and disease-specific survival rate after laser surgery and radiotherapy of T1a glottic carcinoma. Method:PubMed, Web of Science, Embase, Cochrane Library,Chinese biomedical literature datebase,CNKI and Wanfang digital journals were searched from the built of the datebases to October 2016 by computer. Literature screening,date extraction and quality assessment were conducted independently by two co-authors,and the meta-analysis was made with Review Manager 5.3. Result:Twelve literatures were included finally, and statistical analysis results showed that radiotherapy was superior to laser surgery in the laynx preservation rate of T1a glottic carcinoma(OR=3.23,95%CI=1.21~8.60,P=0.02) , overall survival rate and specific disease survival rate were not significant different between laser surgery and radiotherapy. Conclusion:Radiotherapy is superior to laser surgery in the laynx preservation rate of T1a glottic carcinoma.
